Woodward|8273-501|Digital Control Module
Description
The 2301D/2301D-EC 8273-501 Digital Control is a device designed for use in power generation and distribution applications. It provides precise control over engine speed and generator load, supporting both droop and isochronous operating modes. The controller is equipped with multiple input/output interfaces to accommodate various types of sensors and actuators, and it can be integrated into larger systems through its communication ports.
Features
- Supports RS-232, RS-422 serial communications for monitoring and control.
- Offers Modbus protocol for integration with plant-level control systems.
- Provides discrete inputs and outputs for interfacing with auxiliary equipment.
- Equipped with analog inputs and outputs for speed, load, and other parameter control.
- Capable of operating in harsh environments with wide temperature and humidity tolerances.
- Includes protection features such as overvoltage on discrete outputs.
Technical Specifications
Power Supply
